The short version

  • Rewards attentive, consistent care.
  • Give it Bright indirect.
  • Water every 7–12 days.
  • Safe around cats and dogs.

The Hoya linearis (Hoya linearis) is a popular houseplant from the Apocynaceae family, native to Himalayas. It is rated Fussy to grow and typically reaches 30–90 cm indoors. Here is everything you need to keep it healthy — watering, light, humidity, feeding, propagation, and pet safety. It is a Moderate grower, putting on most of its growth in the warm, bright months of spring and summer.

⚖️Pros & cons

Pros

  • Non-toxic to cats and dogs
  • Flowers indoors
  • Beautiful trailing habit

Cons

  • Needs high humidity to look its best
  • Fussy about routine and conditions

💧Watering

Water your Hoya linearis roughly every 7–12 days, letting the top few centimetres of soil dry out between waterings. Always empty the saucer so the roots never sit in water — overwatering is the most common way this plant is lost.

Not sure when to water? Push a finger 2–3 cm into the soil and water only when it feels dry at that depth — a cheap moisture meter or the weight of the pot works too. Water thoroughly until it runs from the drainage holes, then tip away anything left in the saucer. Soft, yellowing lower leaves usually mean too much water; crispy, curling leaves usually mean too little. Always ease off in the darker months, when the plant drinks far less.

☀️Light & placement

The Hoya linearis likes bright, indirect light — near a window but out of direct midday sun, which can scorch the leaves.

Set it right beside an east window, or just back from a south/west one behind a sheer curtain, so it gets plenty of light without direct midday rays on the leaves. Rotate the pot weekly for even growth, and dust the leaves so they can drink in the light.

🌡️Temperature & humidity

Keep it between 13–24 °C and away from cold draughts and heating vents. It prefers High humidity; if your air is dry, group it with other plants or use a humidifier.

🪴Soil & feeding

Plant it in chunky, airy mix (bark + perlite). Feed with a diluted balanced feed monthly in spring and summer, and stop feeding in autumn and winter when growth slows.

🗓️Season-by-season care

SeasonWateringWhat to do
Spring (Mar–May)Resume regular watering as growth restarts.The main growing season begins — start feeding again, repot if it is pot-bound, and take cuttings now for the best success.
Summer (Jun–Aug)This is the thirstiest season; check the soil more often.Keep feeding on schedule, watch for pests in the warmth, and shield the leaves from scorching midday glass. Higher humidity is welcome.
Autumn (Sep–Nov)Let the soil dry a little longer between waterings.Taper off feeding as growth slows, and move the plant away from cold windows and doorways before the first chills.
Winter (Dec–Feb)Water sparingly — overwatering now is the number-one killer.Stop feeding, give it the brightest spot you have, and keep it away from radiators, heat vents, and cold draughts.

🪟Repotting

Repot roughly every 2 years, ideally in spring as growth picks up. Move up just one pot size (2–3 cm wider) with drainage holes — too big a pot holds water and invites root rot. Signs it is time: roots creeping from the drainage holes or circling the surface, water running straight through, or growth that has stalled. In the years you do not repot, scrape off and replace the top few centimetres of soil.

✂️How to propagate, step by step

Spring and early summer, during active growth, give the best success. Here is how to do it, step by step:

stem cuttings in soil

  1. Cut a 10–15 cm stem just below a node and remove the lower leaves.
  2. Dip the cut end in rooting hormone if you have it (optional).
  3. Push it into moist, well-draining mix and firm the soil around it.
  4. Cover loosely with a clear bag to hold humidity, and keep in bright, indirect light.
  5. After a few weeks, a gentle tug that meets resistance means roots have formed — remove the bag and grow on.

stem cuttings in water

  1. Choose a healthy stem and cut a 10–15 cm piece just below a leaf node with clean, sharp scissors.
  2. Strip the leaves off the lower third so no foliage will sit under water.
  3. Stand the cutting in a glass of room-temperature water with at least one node submerged.
  4. Keep it in bright, indirect light and refresh the water every few days.
  5. When the roots are 3–5 cm long (usually 2–4 weeks), pot it into moist mix and keep it a little humid while it settles in.

🐛Pests & prevention

The usual indoor pests are spider mites (fine webbing, speckled leaves), mealybugs (white cotton-wool tufts), scale (small brown bumps), and fungus gnats (tiny flies from soggy soil). Inspect any new plant before it joins the others, wipe the leaves now and then, and let the topsoil dry to keep gnats away. At the first sign, isolate the plant, wipe or rinse off what you can, and treat with insecticidal soap or neem oil every week until it is clear.

🐾Is it safe for pets?

Good news for pet owners: the Hoya linearis is considered non-toxic to both cats and dogs by the ASPCA. It is one of the safer choices for homes with animals, though eating any plant can still cause mild stomach upset.
Toxicity information is a general guide based on ASPCA data. If your pet or child may have eaten any part of a plant, contact a vet or poison control right away.

Frequently asked questions

Is the Hoya linearis toxic to cats and dogs?

No — the ASPCA lists the Hoya linearis as non-toxic to cats and dogs. Eating a lot of any plant can still cause mild stomach upset.

How often should I water a Hoya linearis?

About every 7–12 days — let the top few centimetres of soil dry out first, then water thoroughly and drain.

How much light does a Hoya linearis need?

Bright indirect. Keep it out of harsh direct midday sun unless it is a full-sun plant.

Why does my Hoya linearis have Brown, crispy tips?

Dry air, or salts and fluoride from tap water. Raise humidity and water with filtered or rested water.

How often should I repot a Hoya linearis?

About every 2 years, ideally in spring. Move up just one pot size when the roots fill the pot or creep out of the drainage holes.

How fast does a Hoya linearis grow?

It is a Moderate grower, with most of its growth in the brighter, warmer months of spring and summer.

How big does a Hoya linearis get indoors?

Usually 30–90 cm indoors, depending on light, pot size, and how long you have had it.

Is the Hoya linearis an air-purifying plant?

It is grown mainly for its looks rather than as an air-purifying plant, though all houseplants add a little greenery and humidity.

Is the Hoya linearis easy to care for?

It can be fussy about humidity and watering, so it rewards attentive care.
